How to Authenticate Your Domain

Authenticating your domain—particularly for email sending—is a proven way to boost deliverability, protect your brand, and prevent spoofing or phishing attacks. It involves configuring three key DNS records: SPF, DKIM, and DMARC.

Why Authenticate Your Domain?

1. Improve deliverability and inbox placement
Email clients (e.g. Gmail, Outlook) check SPF and DKIM records, and failing those checks often sends your message straight to spam. Authenticated emails have a much higher chance of landing in the inbox—studies show around 98 % delivery rates when both pass.

2. Protect your brand from spoofing
Authentication prevents attackers from sending phishing emails posing as your organization. Unauthenticated domains are easy targets for fraudsters and hurt customer trust.

3. Control email handling via DMARC policies
DMARC allows you to instruct receivers—such as to quarantine or outright reject unauthenticated messages—while giving you reporting on failures so you can fine-tune policies over time.

4. Boost sender reputation
ESP and mailbox providers start to track your domain’s reputation. Authentication ensures they attribute your sending accurately and favor your domain in their algorithms.

How to Authenticate Your Domain

Step 1: Set Up SPF (Sender Policy Framework)

  • List out all IP addresses and third‑party services authorized to send emails (e.g. Mailchimp, Google Workspace).

  • Create a DNS TXT record like:

    v=spf1 ip4:1.2.3.4 include:sendgrid.net -all
    
  • Publish it to your domain’s DNS and test it using tools like MXToolbox.

Step 2: Enable DKIM (Domain Keys Identified Mail)

  • Generate a public/private key pair.

  • Publish the public key in a DNS TXT record under a selector subdomain like selector._domainkey.yourdomain.com.

  • The mail server signs outgoing messages using the private key; recipients verify them using the DNS-stored public key.

Step 3: Publish a DMARC Record

  • Add a TXT record at _dmarc.yourdomain.com such as:

    v=DMARC1; p=none; rua=mailto:[email protected]; pct=100
    
  • The p= tag defines policy (none/quarantine/reject), while rua= addresses reporting.

  • Monitor and gradually enforce stricter policies as your authenticated results improve.

Example Setup Summary

Protocol Purpose DNS Record Example
SPF Authorizes sending servers v=spf1 ip4:192.0.2.0/24 include:mailprovider.com -all
DKIM Adds cryptographic email signature selector._domainkey TXT "k=rsa; p=PUBLICKEY"
DMARC Policy & failure reporting _dmarc TXT "v=DMARC1; p=reject; rua=mailto:[email protected]"

Tips & Best Practices

  • Start with a relaxed DMARC policy (p=none) so you can monitor without risking legitimate mail being rejected.

  • Test thoroughly using inbox-sharing tools to ensure SPF, DKIM, and DMARC pass before tightening policy .

  • Include all sending sources—forgetting one (e.g. your CRM or newsletter provider) may lead to failing authentication.

  • If your domain doesn’t send mail, publish a DMARC policy with p=reject to stop spammers from abusing it.

Why It Matters

Email authentication isn’t just a technical step—it’s essential infrastructure:

  • It builds trust with mailbox providers and recipients.

  • It prevents misdeliveries, false flags, and protects your reputation.

  • It hardens your defense against domain spoofing and phishing 

Even email marketers on forums like Reddit strongly advise domain authentication to ensure legitimate messages are not marked as spam—or lost entirely.

Final Takeaway

Authenticating your domain via SPF, DKIM, and DMARC is a foundational step for secure, reliable email communication. It significantly improves deliverability, protects your brand from impersonation, and allows you to control how unauthenticated mail is handled. While setting it up takes coordination with DNS and your email provider, the reward is stronger sender reputation and consistent inbox placement.

Donation Thank You

Thank you. Not the plastic kind. Not the customer-service smile with dead eyes kind. I mean it. Really.

You could’ve spent that money on caffeine, comfort, or another hit of digital distraction. But instead, you threw it into this weird little corner of the internet — my corner. You helped keep this mad, messy thing alive. And that’s no small thing.

In a world wired to take, you gave. In a culture of scroll-past indifference, you stopped, saw, and said this matters. That means more than I can put into words, but I’ll keep trying — because that’s the deal here. Blood on the page. Truth over polish. Gratitude without the greeting card gloss.

Your support isn’t just a donation. It’s oxygen.

So thank you — for fueling the work, for trusting the voice, for helping me keep shouting into the void.

And if the void ever shouts back? I hope it says your name.

All the best to you – John

The 80% Approach by Dan Sullivan

The 80% Approach by Dan Sullivan is a productivity and mindset strategy that encourages people to focus on progress rather than perfection. Sullivan, a renowned business coach and founder of Strategic Coach, developed this concept to help individuals and teams achieve more by avoiding the common trap of striving for 100% perfection. By concentrating on completing tasks to 80% of their potential, you can save time, reduce stress, and maintain momentum. Here’s a deeper exploration of this approach.

The Core Idea

The 80% Approach centers on the principle that getting a task done to 80% of its full potential is often enough to move forward effectively. Many people become stuck trying to perfect every detail, which slows progress and leads to procrastination or burnout. This approach emphasizes that the remaining 20%—the fine-tuning, extra polishing, or minor improvements—can be addressed later, if necessary.

For example, if you’re creating a presentation, instead of spending countless hours perfecting every slide, focus on achieving an 80% complete version that covers the essential points. Once that’s done, you can refine it if there’s time or receive feedback to make incremental improvements.

Why the 80% Approach Works

  1. Prevents Perfection Paralysis
    Many individuals delay completing tasks because they fear they’re not perfect. The 80% Approach eliminates this roadblock, enabling action and progress.
  2. Encourages Momentum
    By focusing on completing tasks quickly and efficiently, you maintain momentum and build confidence. Progress inspires more progress.
  3. Facilitates Collaboration
    Releasing work at 80% completion allows for early feedback from others. This collaborative process often leads to better results than working in isolation until you feel it’s “perfect.”
  4. Saves Time and Energy
    Spending disproportionate time on the final 20% of a task often yields diminishing returns. Completing tasks to 80% allows you to allocate energy to other priorities.

Applying the 80% Approach

  1. Shift Your Mindset
    Accept that “done is better than perfect” and embrace the idea that imperfection doesn’t mean failure. This mindset shift allows you to move forward without hesitation.
  2. Prioritize Essentials
    Identify the core elements of a task that need to be completed to meet the goal. Focus on those aspects rather than sweating over minor details.
  3. Iterate and Improve Later
    Deliver your work at 80% completion and use feedback or additional time to make incremental adjustments. This iterative process ensures continuous improvement without stalling progress.
  4. Delegate Effectively
    If working with a team, communicate the 80% standard. This helps set realistic expectations and encourages faster delivery of initial drafts or ideas.

Example in Practice

Suppose you’re writing an ebook. Using the 80% Approach, you would first draft the content focusing on delivering the key insights and structure. Instead of spending weeks perfecting grammar, formatting, or visuals, you’d create a working version that’s good enough to share with editors or reviewers for feedback. This approach ensures you make steady progress and deliver value without overthinking.

The Bigger Picture of the 80% Approach

Dan Sullivan’s 80% Approach ultimately fosters a culture of action, learning, and growth. It reminds us that perfectionism is often the enemy of productivity. By prioritizing progress over perfection, you can achieve more in less time, maintain momentum, and leave space for innovation and collaboration. The 80% Approach isn’t about settling for mediocrity—it’s about understanding that consistent progress leads to exceptional outcomes.
